Question: Vertical Line Test

Answer: Simple test use to determine if a graph represents a function.

==================================================

Question: Increasing Interval

Answer: A function f(x) is increasing in an interval if the graph is rising right.

==================================================

Question: Decreasing Interval

Answer: A function f(x) is decreasing in an interval if the graph is falling right, (rising left).

==================================================

Question: Constant Interval

Answer: A function f(x) is constant in an interval if it is NOT rising right, or rising left.

==================================================

Question: Relative Maximum

Answer: A point at which a function changes from increasing to decreasing.

==================================================

Question: Greatest Integer Function

Answer: f(x) = [x]. Looks like a series of steps when it is graphed.

==================================================

Question: Symmetrical to x-axis

Answer: The graph contains (x, y) and (x, -y), and is not a function.

==================================================

Question: Even Function

Answer: A function that is symmetrical to the y-axis, and contains (x, y) and (-x, y).

==================================================

Question: Odd Function

Answer: A function that is symmetrical to the origin and contains (x, y), and (-x, -y).
